Question 11

+3 marksOne or more correct options

You are comparing rule-based machine translation (RBMT), statistical machine translation(SMT), and example-based machine translation (EBMT) for translating a set of sentences between English and Spanish. Based on the characteristics of these techniques, which of the following statements are correct?

Select all that apply.

  1. A

    RBMT heavily relies on linguistic resources such as bilingual dictionaries and grammar rules, making it less effective for low-resource language pairs.

  2. B

    EBMT does not rely on explicit linguistic rules but instead retrieves and reuses translation examples, making it highly dependent on the quality of the example database.

  3. C

    RBMT has a strong ability to generalize to unseen inputs due to its reliance on manually crafted linguistic rules.

  4. D

    SMT can handle unseen words better than RBMT by leveraging subword-level probabilities for translation.

  5. E

    EBMT achieves higher translation accuracy than SMT in domain-specific scenarios if the example database contains relevant matches.
